Reply to "Comment on 'Ground State of the Strong-coupling Hubbard Hamiltonian: A Numerical Diagonalization Study'"
(American Physical Society, 1989)
We establish the correctness of our exact diagonalization results for the ground state of the effective strong-coupling Hubbard Hamiltonian, and the consistency of their interpretation within the finite-size system studied. ...
Microscopic Model of Heteroepitaxy of GaAs on Si(100)
(American Physical Society, 1989)
A new microscopic model of heteroepitaxial growth is introduced using GaAs on Si(100) as a prototype. This model takes into account specific features of surface topology, predicts that in the prototype system conventional ...
